New Roy listings appear here as they list, and sold homes drop off. The read on what makes one legal is just below.
Buying here
Sort permitted from existing before you tour.
A second kitchen, a private entrance, or a detached structure do not make an accessory dwelling legal on their own; the two things that decide it are whether the space is permitted with Roy City and whether every below-grade bedroom has real egress. Tell me what layout you need, and I will have the Roy-area partner agent I work with pull the permit history on any home you flag.

The local read
What an accessory dwelling really means in Roy.
An accessory dwelling is a property feature, not a promise. On a Roy listing it means a secondary living space that can function on its own: a second kitchen, its own bathroom, a separate exterior entrance, and sometimes a separate utility meter. The words move around. A basement apartment is a lower level built out that way, a casita is usually a detached unit set apart from the house, and a mother-in-law suite is usually an attached apartment on the main or upper floor. The search shows up across the Wasatch Front for two honest reasons, room for an extended household under one roof and a separate suite where the unit is legal, and both turn on the same homework, which is whether the space is actually permitted.
Roy is good ground for this search, and the form it takes here is mostly the basement apartment. The city sits on the flat lake plain west of I-15, where the frost line is deep and basements are the norm across every era. Roy was mostly framed in the 1950s and 1960s Hill Air Force Base boom, so the east and central core along the 5600 South and 1900 West corridors carries a deep stock of full-basement ramblers and split-levels, and a great many of those basements were finished over the years to double the living space. Adding a second kitchen and a private entrance to that kind of full basement is exactly the conversion these listings describe. A split-level or split-entry floor plan, where the layout puts a grade-level door a half-flight down, lends itself to the same conversion as much as anything in town, and an attached mother-in-law suite can turn up in the later west side toward the FrontRunner station and the Hooper line, the 1980s-to-2000s two-stories and split-entries, often on newer systems. Roy is a built-out grid of standard suburban lots, so a fully detached casita is the rarest shape here and would be a find rather than an expectation.
Here is the part that matters more than the photos. A finished basement is not the same as a legal apartment, and neither is a converted room or a detached structure out back. A second kitchen and an outside door do not make a unit conforming on their own, and a great many existing accessory units in older Roy housing were finished without permits or built before today's rules. That is not a reason to walk away, but it is the reason to verify rather than assume. The two questions that decide everything are whether the unit is permitted with Roy City and whether it has its own legal egress, meaning a code-sized window well or door out of every below-grade sleeping room. What an accessory dwelling is allowed to be on a given property depends on that parcel's zoning, so the answer is property-specific, not citywide.
Treat any income angle with the same caution. I will not put a rent number or a payment number on a page like this, because what a unit could do depends entirely on its legal status, the specific space, and rules that change, and a non-conforming unit cannot be counted on at all before you count on the income. What I can do is point you at the right stock. The older-core ramblers are the natural hunting ground, so the single-story page is a useful next stop, and the no-HOA page covers the older lots with the most freedom to use the space. If you only want the extra square footage and not a second kitchen, the homes with a basement page is the wider search, a different intent than this one. Earlier in the process than show me listings? Start with the Roy guide, and when a home below reads right, that is the moment to reach out.
What counts as an accessory dwelling
-
The form it takes: in Roy most of these are basement apartments, since full basements are the norm across the older east and central core. Attached mother-in-law suites turn up in the newer west-side stock, and a detached casita is rare on Roy's standard lots, so read the listing for where the space actually sits.
-
Second kitchen: a full or kitchenette setup is the core marker. A finished basement or a spare suite with no kitchen is just extra space, not a separate unit, so read the listing for the actual layout.
-
Separate entrance: the second front door of the page title. A private exterior entry, often a walk-down or a side door, is what makes the space usable on its own rather than a through-the-house extension. Roy's split-levels and split-entries lend themselves to this.
-
Separate egress: every sleeping room below grade needs a code-sized window well or a door to the outside. This is a safety item and a legality item at once, and it is the first thing to confirm in person.
-
Separate utilities: some units have their own gas or electric meter, or at least split HVAC. Worth noting that Roy bills culinary water and secondary irrigation on two separate accounts, so check both. A separate meter is a convenience, not proof of legality.
The local map
Where the accessory units actually are.
Homes with a second living space turn up across Roy, but the forms concentrate in a few patterns, and the basement apartment is by far the dominant one. Here is where to look, and the due-diligence note attached to each.
The 5600 South corridor and the base edge
From Exit 338 west past the Roy Gate, the 1950s and 1960s boom blocks hold ramblers and split-levels over full basements with sixty-year-old trees. It is the most likely place to find a real separate suite, and also the most likely to find one finished without a permit, so verification matters most here. Honest note: this corridor is closest to the Hill flightline, so you will hear the jets on flying days. Tour on a weekday and listen.
East Roy and the 1900 West corridor
The older mid-century stock nearest I-15 and the Riverdale line carries deep finished basements on the city's most established blocks. Shortest freeway runs and the everyday-retail spine are minutes away. Many of these basements were finished decades ago, so the permit history and the panel and furnace ages all deserve a close look.
Central Roy and the Midland Drive diagonal
Housing along the Midland Drive diagonal runs the full mid-century-to-1990s range, so a built-out lower level here can be an older full basement or a younger one, depending on the block. Confirm the era of the specific home before you assume which kind of conversion you are looking at.
West Roy and the 4000 South corridor
The 1980s-to-2000s two-stories and split-entries filling the blocks toward Roy Station and the Hooper line tend to have newer systems and larger footprints, which can make a comfortable second kitchen and a real bedroom downstairs more workable, and this is where an attached mother-in-law suite is most likely to turn up. A newer build is more likely to have been finished with permits, but you still verify it.
Split-level and split-entry floor plans
Split-level and split-entry are genuine Roy signatures, and the layout lends itself to a lower level with its own grade-level door. The split design can put a private entrance just a half-flight down, which is why so many conversions started here. Confirm the egress windows on the bedrooms below before you read the space as a legal suite.
Larger and taller basements
The bigger two-story and later-era plans often have the deepest, tallest lower levels, which is the difference between a livable separate suite and a short, dark basement. Stand in the space and check the ceiling height and the natural light, not just the listing photos.
Before you tour: what to actually check
Is it permitted: ask the listing agent for the permit history and confirm the unit's status and the parcel's zoning with Roy City. A second kitchen and a side door do not make a unit legal on their own.
Egress on every bedroom: each sleeping room below grade needs a code-sized egress window and well, or a door to the outside. Look at the actual window wells, not just the listing photos.
Conforming vs. existing: many older Roy accessory units are non-conforming, finished before today's rules or without permits. Understand exactly what you are buying and what can and cannot be relied on.
Separate systems: check whether the kitchen, HVAC, and any meter are genuinely separate, whether that is inside a basement, an attached suite, or a detached structure, and whether the wiring and gas work were done to code and inspected.
Ceiling height and light: an older Roy basement can be low. Stand in it and check the ceiling height, since Roy's flat lake-plain lots do not offer a walkout or daylight option the way a sloped lot elsewhere in the county might.
Two water bills and the rest: Roy bills culinary water on a city account and secondary irrigation on a separate district account, so check both, and on any older-core home, date the roof, furnace, electrical panel, and sewer lateral.

Quick answers
ADU and casita shopping, answered.
It is a secondary living space that can function on its own, and Roy listings use a few different words for it. The most common form here is a basement apartment, a lower level built out with a second kitchen, its own bathroom, and a separate exterior entrance. A casita usually means a detached unit set apart from the main house, and a mother-in-law suite usually means an attached apartment on the main or upper floor. All of them are property features describing the space, nothing more. The big thing to know is that a second kitchen and an outside door do not make a unit legal on their own, so the real work is confirming whether it is permitted and conforming with Roy City and what the specific parcel's zoning allows.
Some are and some are not, which is exactly why you verify rather than assume. An accessory dwelling has to be permitted with Roy City to be treated as a separate dwelling, and what is allowed depends on the parcel's zoning. Many existing units in Roy's older mid-century homes were finished over the years without permits or were built before today's rules, so they are non-conforming. That is not a dealbreaker by itself, but you need to know which one you are buying. Confirm the zoning, the permit history, the unit's status, and the egress independently before you rely on it, and I will help line up those checks.
Most often in the 1950s and 1960s east and central core, the ramblers and split-levels along the 5600 South and 1900 West corridors, which sit over the city's deepest stock of full finished basements and carry most of the basement apartments. Roy's split-level and split-entry floor plans are a natural fit for this conversion, since the layout can put a grade-level door a half-flight down. The newer west-side two-stories toward the station can carry an attached mother-in-law suite too, often on newer systems. Roy is a built-out grid of standard suburban lots, so a fully detached casita is the rare exception here rather than the norm. The live listings above are the honest count on any given week.
Only where the unit is legal, and that is the whole point of the verification. A permitted, conforming accessory dwelling is a different thing from a non-conforming space that happens to have a kitchen, and the rules around accessory dwellings can change, so this is a question to confirm with Roy City for the specific property and its zoning, not to assume from the listing. I will not put a rent figure on a page like this, because it depends entirely on the unit's legal status and the specifics, but I can connect you with a local agent who will get you straight answers on what the city allows.
Egress is a legal, code-sized way out of every below-grade sleeping room, usually an egress window with a window well sized for a person to climb out, or a door to the outside. It is both a safety requirement and a piece of what makes a basement bedroom or apartment count as legal living space. It matters most on the basement units that make up most of this search, and it is the first thing to confirm in person, because a room marketed as a bedroom downstairs is not really one without it. We check the actual window wells, not just the photos.
Tell me the budget, the part of Roy you want, and whether you need a fully permitted suite or are open to an existing space to verify, and I will connect you with a Roy-area partner agent and flag matching listings as they go live. Pair that with a conversation about financing so you can move when the right suite home lists, since these are a narrow slice and they do not sit long.
